Workplace bullying: individual hostility, poor work environment or both? Exploring competing explanatory models in a single longitudinal study

PURPOSE

A central focus of research and literature on workplace bullying is the importance of explanatory factors such as individual dispositions (i.e., the vulnerability hypothesis) and work environment factors (i.e., the work environment hypothesis). Although several studies address the importance of the two approaches, as well as their individual and combined effects, the unique contribution of each of the competing approaches remain unexplored in a single longitudinal study.

METHODS

Based on Affective Events Theory, we explore the contribution of work environment and individual hostility in the occurrence of workplace bullying over time, using two-wave survey data, collected with a 6-month time lag among 152 employees from 7 private and public workplaces.

RESULTS

Results confirmed that work environment factors predicted later exposure to bullying. Exposure to workplace bullying at T1 was also related to a poor work environment at T2. Results further showed that higher exposure to workplace bullying at T1 and T2 was related to higher levels of almost all aspects of individual hostility over time. Moreover, poor working conditions especially in T1 predicted individual hostility at T2.

CONCLUSION

The present study thus documents that a poor work environment fosters bullying, and when bullying exists in a workplace, this elicits interpersonal hostility. Results points to the importance of addressing, through research and practice, work environment factors as predictors of workplace bullying.

Links Between Early Personal Characteristics, Longitudinal Profiles of Peer Victimization in School and Victimization in College or at Work

This study used a longitudinal design from age six through age 19 (N = 1206 (603 girls)) to examine the associations between anxious-withdrawal and reactive aggression during childhood, distinct profiles of peer victimization from kindergarten to grade 11 and victimization in college or at work in emerging adulthood. In particular, it was tested whether the predictive effect of personal characteristics on victimization in emerging adulthood would be mediated via chronic peer victimization experiences during the school years. Teachers evaluated children's personal characteristics, whereas peer nominations and self-reports were used to assess victimization. Control variables included sex, parent-reported harsh parenting and SES. Longitudinal latent profile analysis revealed four distinct profiles of peer victimization during the school years: Consistently-Low (39.7%), Low-Moderate (42.8%), High-Decreasing (8.8%) and High-Increasing-Decreasing (8.7%). A subsequent 3-step regression-based path analysis supported the mediation hypothesis - albeit differently for different profiles of peer victimization. Specifically, compared to a Consistently-Low profile of peer victimization in school, a High-Decreasing profile was predicted by reactive aggression, but not anxious-withdrawal. In contrast, a High-Increasing-Decreasing profile was predicted by reactive aggression and anxious-withdrawal. In turn, elevated peer victimization profiles were associated with higher levels of later victimization in college or at work. The indirect effects linking the childhood behaviors to later victimization in college or at work - via elevated peer victimization profiles during childhood and adolescence - were significant. These results highlight the need for tailored interventions to optimize reactively aggressive or anxious-withdrawn children's response strategies to challenging and potentially threatening peer interactions.
